Fermi surface transformation at the pseudogap critical point of a cuprate superconductor
Nature Physics, 2020The nature of the pseudogap phase remains a major puzzle in our understanding of cuprate high-temperature superconductivity. Whether or not this metallic phase is defined by any of the reported broken symmetries, the topology of its Fermi surface remains

The de Haas - van Alphen spectrum of is calculated and compared with the experimental spectrum for continuously varying directions of the magnetic field. The local density approximation to spin-density functional theory is used for the self-consistent calculations treating the U 5f electrons as itinerant and including spin - orbit coupling.

Physica Scripta, 1990 Recent work using high resolution angle-resolved photoemission to determine the Fermi surfaces for surface-localized electronic levels on several metal surfaces is reviewed. We examine our fundamental motivation for these studies and their relation to phenomena observed in other branches of chemistry and physics.

The Fermi Surface of CeSb [PDF]
, 1987 A central issue of f-electron metals is the importance and description of hybridization between the f and conduction electrons. The strength of the hybridization controls the general nature of the behavior:1,2 strong hybridization leads to purely itinerant behavior with properties similar to those of the transition metals, weak hybridization leads to ...

Evidence for a spinon Fermi surface in a triangular-lattice quantum-spin-liquid candidate
Nature, 2016A quantum spin liquid is an exotic quantum state of matter in which spins are highly entangled and remain disordered down to zero temperature. Such a state of matter is potentially relevant to high-temperature superconductivity and quantum-information ...

Fermi surface in the absence of a Fermi liquid in the Kondo insulator SmB6
Nature Physics, 2017The search for a Fermi surface in the absence of a conventional Fermi liquid has thus far yielded very few potential candidates. Among promising materials are spin-frustrated Mott insulators near the insulator–metal transition, where theory predicts a ...

Abstract The electronic band structure of CeAl2 in the cubic Laves structure has been calculated. The Ce f-electrons were explicitly treated as core electrons. The calculated Fermi surface is found to be consistent with recent de Haas-van Alphen effect results, thereby corroborating that in CeAl22, the f-electrons are essentially localised and ...

Abstract We have measured the magnetoresistance and the de Haas-van Alphen (dHvA) effect in CeSn 3 . The magnetoresistance increases in all field directions. This result claims that CeSn 3 is a compensated metal. Compared to an uncompensated metal LaSn 3 , the 4f electrons in CeSn 3 become itinerant electrons.
